Support for LabelManager Wireless PnP

[thinkl33t]

Some initial work on LabelManager Wireless PnP

• add auto cut to end of print statement (this is added to every print - in testing with a LabelManager PnP this doesn't effect anything on devices without a cutter)
• add 24mm to valid label sizes

still to do:

• printer doesn't output anything when cold-booted until it has been printed to once by another application - currently i'm using dymoconf/render-label.py and sending it to port 9100 on the printer to do this initialization
• when things are printed out, they come out very squished - i suspect i need to fiddle with LABELER_PRINT_HEAD_HEIGHT_MM depending on the specific labeller but i could be wrong here - i can't find any codepaths that differ between devices at the moment

The current situation with the codebase is unfortunately a bit precarious. We have forked into a develop branch which is unfortunately broken, but that adds some stuff to sanely support other devices. There's still a bit of cleanup to do before we can bring it into main though, so I'd recommend keeping this PR slim to avoid duplicating work and increasing the likelihood that we can merge.

I appreciate a lot that you're showing your work early. For purely organizational purposes I'm going to convert this to a draft. Please feel free to mark it as "ready for review" and ping us whenever you'd like us to take another look at it.

After some more experimentation, sending the cut for every printer seems to crash out printers with no cutters, so i'm going to try and rework this against your develop branch :)

[maresb]

That's strange, which printers are you testing against? I'm fairly confident that with my PnP the cut command was a noop, but I don't have it at the moment.

Please be warned that there's no timeline for merging develop into main, just to calibrate your expectations.
